The annual Great Migration of over 1.8 million wildebeest, almost half a million gazelles, and nearly a quarter million zebra starts out from the south of the Serengeti (Ndutu Plains), with the birth of over half a million calves between January and March. The air during these months is full of new life and action, and predators constantly hunt for babies when thousands of calves are born each day. Lions, leopards, cheetahs, wild dogs, hyenas and other predators and scavengers follow the herds, so get ready to keep your eyes peeled.
